Theresa May threatens 'no Brexit at all' as senior Tories put new referendum on table

Earlier, Labour MP Gavin Shuker asked an interesting question. He said the UK is becoming more attractive place for sex traffickers due to stricter laws in nearby countries such as France and the Republic of Ireland.

May says the Home Office has provided funds for a study into sex work in England and Wales, which will report back in the spring.

Conservative MP Crispin Blunt raises the case of Matthew Hedges, a 31-year-old Briton who has been jailed for life on spying charges in the United Arab Emirates (UAE).

May says the Foreign Secretary is urgently looking into this case and she sends her condolences to his family.

Brexit klaxon: Nigel Dodds, the DUP leader at Westminster, asks if May deleted a section from last year's joint report that said Northern Ireland would have a final say on whether it diverged from single market rules. It is not in the withdrawal agreement.

May says these are decisions for the UK as a whole and the joint report referred to decisions by the Northern Ireland assembly - which is still suspended.

That's it for PMQs for the week.

Jeremy Hunt is now answering an urgent question on the need for a ceasefire in Yemen.

He says the conflict has escalated to become one of the worst humanitarian disasters in the world, where a third of the population are dependent on international aid.

Statistics cannot convey the enormity of this tragedy, he says, which is a 'man-made humanitarian catastrophe'.

Hunt called on all sides to set aside their arms and seek a peaceful political settlement. He has raised this in Saudi Arabia and Iran on recent visits.

The aim of the UK-sponsored UN Security Council resolution on Yemen is to "relieve the immediate humanitarian crisis and maximise the chances of achieving a political settlement," he said.

Emily Thornberry, shadow foreign secretary, says MPs have called for the government for more than two years to table a ceasefire motion. Hunt has not buried his head in the sand and deserves credit for this.

She says there is a lot to welcome in the draft resolution, which demands an immediate cessation of hostilities in Hodeidah, Yemen's main port city.

Ms Thornberry added: "Can the Foreign Secretary tell us why this latest resolution fails to spell out what compliance with the resolution will be monitored and by whom, and what sanctions will apply to any party who breaches its terms whether in terms of the ceasefire or the restriction of humanitarian aid?"

She also pressed him on whether there would be independent investigations into violations of international law - and whether he discussed this in Saudi Arabia.

All that Jean-Claude Juncker can offer Theresa May is a fudge in the wording of the non-binding part of the Brexit deal, the political declaration on the future trade relationship between the EU and the UK, says the Indy's John Rentoul.

A government minister has been criticised after he suggested poor families could "move house" or “take in a lodger” to ease financial pressures caused by the benefit cap.
